The mechanical seal IN0340.9BQQVGG is a precision-engineered component designed for reliable shaft sealing in demanding industrial pump applications. This model belongs to the IN9B/IN8B series within the comprehensive catalog of mechanical seals, offering a robust solution characterized by its balanced design and high-performance material composition. Its construction features a stationary face and a rotating face, both manufactured from silicon carbide (карбид кремния), ensuring exceptional wear resistance, low friction, and superior chemical inertness against a wide range of aggressive media.

Key dimensional parameters of this mechanical seal are critical for correct installation and optimal performance. The seal is engineered for a shaft diameter (d1) of 34.9 mm. The external diameter of the fixed part (d7) is 60.33 mm, while the outer diameter of the moving part (d3) measures 61 mm. The overall seal length (L3) is 45 mm. These precise розміри торцевого ущільнення guarantee proper fitment within the seal chamber and correct axial positioning. The metallic structural components are constructed from AISI304 stainless steel, providing excellent corrosion resistance. The secondary sealing element is made from NBR (Nitrile Butadiene Rubber), a material chosen for its good compatibility with oils, water, and many fluids within a standard temperature range.

A defining feature of the IN0340.9BQQVGG is its design type: с прижимным кольцом (with a clamping ring). This design facilitates secure and straightforward installation, ensuring the stationary seat is positively locked and sealed against the housing. The seal is classified under grade 9B, indicating its specific configuration and performance characteristics suitable for standardized applications. When selecting from the каталог торцевих ущільнень, this model represents a reliable choice for general service in chemical processing, water treatment, and various industrial pumping systems where durability and leak-free operation are paramount. Its material synergy and precise engineering ensure long service life and reduced maintenance intervals.
